Answer:
Option C.
Step-by-step explanation:
The given given sequence is
1, –3, 2, 5, –4, –6
We need to find the pairs of consecutive terms of the sequence and their product.
Pairs of consecutive terms | Product
1, -3 -3
-3, 2 -6
2, 5 10
5, -4 -20
-4, -6 24
Here the product of three pairs of consecutive terms is negative.
The number of variations in sign for the sequence is 3. Therefore, the correct option is C.
Answer:
1) The worker can keep the soup in a container with a large surface area as evaporation will occur faster
2) The worker and keep the soup near a fan, cooling the soup
3) The worker keep the soup in a dry area as moisture reduces the rate of evaporation
2/5 ÷ x = 4/5
multiply both sides by x to get it out of the denominator.
2/5 = 4/5x
now divide each side by 4/5 to get x by itself.
2/5 ÷ 4/5 = x
divide fractions by multiplying the reciprocal of the divisor.
2/5x × 5/4 = x
10/20 = x
1/2 = x
So 2/5 divided by 1/2 =4/5
The equation for profit is expected to be
daily profit = (profit on plate)*(number of plates) +(profit on cup)*(number of cups)
We are told that
profit on plate = k
profit on cup = k-1
Matching these to the expression above, we find
x = number of plates
y = number of cups
You are asked what y represents. It is
A. The number of cups sold in one day.
